DIE FOR MAKING SHUTTLE-BINDERS.

SPECIFICATION forming part of Letters Patent No. 328,994, dated October 27, 1885.

Application filed March 31, 1885.

To aZZ whom it may concern.-

Be it known that we, HORACE WY- MAN and LYMAN F. GORDON, of Worcester, county of Worcester, and State of Massachusetts, have invented an Improvement in Dies for Shuttle-Binders, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

Shuttle-boxes now used in all regular standard looms have shuttle-binders which are composed of cast or malleable metal. If of cast metal, the binders are apt to be broken by the strain of the parts, and binders of either plain cast-iron or of malleable iron are heavy.

Our invention has for its object to produce a light-weight binder; and to do this and secure the necessary strength we have produced a wroughtmetal or low-grade steel binder, the metal used being that which is adapted to be shaped in dies.

Our present invention consists in the dies employed to shape the said shuttle-binders, as will be described.

Figure l is a face View of the recessed or lower part of the die; Fig. 2, a face view of the upper or ribbed part of the die having the projection, and adapted to co-operate with the die having the recess. Fig. 3 is an inner side elevation of the shuttle-binder produced in our novel-shaped dies; Fig. 4, an outer side view of the said shuttle-binder; Fig. 5, a longitudinal section taken through both dies, the binder being shown therein in elevation and Fig. 6, a cross-section in dotted line a: at, Fig. 5.

A is the recessed lower part of the die, and B the upper or ribbed part.

The face of the upper part of the die A is recessed or cut out to leave parallel walls ac, which are connected by preferably curved or inclined walls I) b with walls 0 c, not so far separated as the walls a a. The walls 0 c are joined by walls d d, either curved or inclined, with other walls, e c, which are separated farther from each other than the walls a a.

The end of die A farthest from the end having the walls 6 e is provided with a recess, 9, which is concaved, as best shown in Fig. 5, and the floor of the recess in the die A is provided with a groove, h, preferably enlarged, as at m. Viewing Fig. 5, it will be seen that Serial No. 160,823. (No model.)

the face of the die A and the floor of the recess therein is inclined downward from the line of the walls 1) toward the walls 6 6, (see p Fig. 1,) and that the groove h in the said recess in the said floor next the concavity g is widened, as at f.

The die B has a rib, n, at its face, which is in line with the recess h, and the face of the said die is curved, as shown in Fig. 5, to conform to that of the die A.

The shuttle-binder produced in the dies described is shown in Figs. 3 and 4, wherein a a represent the body of the binder, it being shaped between the walls a a; c c, the neck of the binder, it being produced between the walls 0 c; c e, the head of the binder produced between the walls e e, and g the hub of the binder, it being produced between the dies in the recess 9. The head 6 in practice is acted upon by the usual protector-finger ofthe loom, and the neck, narrower than the head 6' or the body a, enables the operator to easily reach past the binder to move a shuttle in the .box by hand. The hub g is subsequently bored to receive a pin or rod, by which the binder is pivoted to the shuttle-box. The re cess h in the die A and the projection m of die B causes the metal of the binder to be struck centrally to form the rib h at the outer face of the binder, and the recess a at its inner side.

The recess 112. results in the production of the shoulder or projection m, and the recess f the enlargement f.

We desire it to be understood that the recesses m and f may be omitted, and so also the groove h and rib a,- but these we prefer to retain; and so, also, if desired, the walls a a for a short distance'near the concavity 9 may be contracted to form concavities at the edge of the binder resembling in shape the neck 0 c.

The shuttle-binder will be produced from a forging shaped to approximate the shape desired for the binder, the forging being, however, left a little thicker than desired for the finished binder, so that when acted upon between the dies the metal may be made to fill all parts of the recessed die.

The walls e c of the head may be of the same distance apart as the walls a a of the body, or of a different width, and the face of the die A may be straight instead of curved,

as shown, or of a different curve, although we prefer this curve.

The, forging placed between the dies described, in order that the shuttle-binder may 5 be perfect in shape, contains more metal than is actually required, the surplus metal leaving the die as fins; but when the binder is removed the fins are cut off in a shearing-die or in other proper manner.

10 We claim 1. Dies, substantially as herein described, for forming shuttle-binders, one part being recessed to form walls a b c d e, and depression 9, the opposed part having its face shaped I 5 to conform to the face of the recessed part of the die, substantially as described.
